Manchester United are reportedly in discussion with Argentine goalkeeper Sergio Romero over a three-year deal to join the Red Devils this summer.

According to the Daily Mail, the Argentine international, who is a free agent after leaving Sampdoria in the summer, has been identified by Louis van Gaal as the perfect replacement for Victor Valdes, who looks certain to leave the 20-times English champions this summer.

The former Barcelona goalkeeper, who signed for the Red Devils during the January transfer window, has been put up for transfer, after he refused to play for the Old Trafford club's reserve team, when the manager had asked to do so.

"Valdes is not selected [for the tour] because he doesn't follow my philosophy. The philosophy is how you play football and how you maintain your match rhythm," said Van Gaal, as quoted by Goal.

"He refused last year to play in the second team. There are a lot of other aspects in the philosophy how you have to play like a goalkeeper at Manchester United."

"When you are not willing [to apply] the principles of that philosophy there is only one way, and that is out," the Dutchman added.

Romero is a regular starter in the Argentina squad and played every minute of the recently concluded Copa America tournament in Chile. The stopper has also been linked with a move to Roma, but it is believed that he is keen on a switch to Old Trafford instead.

Meanwhile, the report has claimed that Valdes is attracting interest from MLS side Seattle Sounders, after Valencia dropped their interest due to the unreasonable demands made by the 'keeper.

Van Gaal is facing a shortage of quality goalkeepers at United, and might have to sign two stoppers as first-choice David de Gea's future also remains uncertain with Real Madrid interested in taking the Spaniard to Santiago Bernabeu.
